Answer:
There is no diagram in this question but the question can still be answered without it.
B. hold the cell membrane together, and proteins move chemicals across the cell membrane
Explanation:
The fluid mosaic model, which describes the structure of the cell membrane, reveals that it contains both lipids and protein constituents. These components, however, performs different functions in the cell membrane of organisms.
The lipid component of the cell membrane, which comprises of glycolipids and cholesterol, hold the cell membrane together while proteins called transport proteins help move chemicals across the cell membrane.
1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.
(Hope this helped. Have a nice day.)
